Sep 16 2019 · The ramming refractory mass used for neutral lining in the induction furnace consists mainly of Al2O3 with the addition of MgO in the matrix which results in in-situ formation of spinel (Al2O3.MgO) at the steel melting temperature. This in-situ spinel formation is associated with a significant expansion of volume to provide a rigid structure.
